I y A I '1' Claim. This invention relates to tile or blocks designedfor-use asforms in laying concreteV or for highways or in forming paths,gutters, driving lanes, etc, or forv any purpose for which such blocks,5, may be used.

An object of the invention is to provide a block of this type made ofappropriate material to enableit to be used as a supporting rwall V'whenl-aying roadmaterial and as a conspicuousroad l() marker-or as a markerfor any purpose when embedded i-n a. road or'floor or drive-way. f lAfurther general object is to provide a block adapted for a great numberof uses yet which is simple `in construction, relatively cheap to pro- 415 duce and durable in service and having-an attractive appearance. n

Further general objects Will become apparentl from the description whichfollows:

Referring to the accompanying drawings, 20 which are made a part hereofand on which similar reference characters indicate similar parts,Figures 1, 2 and 3 show three different types of plastic block, eachembodying principles ,of my invention, Figure 4 is a section of aroadway showing the drive lanes formed of blocks forming a -part of thisinvention in which the.' blocks shown in Figure 1 are used, l Figure 5,a vertical section through the wall 30; of y a pool or tank or reservoirwhich walls are constructed of blocks such as that shown in Figure 2. lf' Figure '6., a Vertical section through a retaining wall showing theends of blocks such as' that 35; shown in Figure 2 and showing insideelevation blocks such as that shown in Figure 1,

(c1. aiin l Figure l5 showsa modi-fied form of block used as a roadmarker, surfacing form and screed,

Figures 16, 17,` 18 and 19 illustrate Various designs whichmay be madein the road bedby the blocks shown in Figure 15, and

Figures 20 and 21 show a form of `mold in which the block shown inFigure is made.

Inthe drawings numeral 3B indicates 'a block which is made out ofsuitable material suchas willserve `as a supportfor concrete or otherroad building material. This block is provide'd'withlongitudinalpassages 3| and 32 vin the latter of which a dowel pinA 33 may be placedto hold the blocks together. Grooves 34 may preferably be placed on thesloping sides of the blocks, these grooves serving to receive plasticmaterial out of which the roadV is built to form dove-tailed or securingledges on the edge of the road.

A passage 35 extends longitudinally through the block near its bottom inorder vto lessen the weight of the block. In the form` shown in Figure 2a groove 36 is Vprovided near the base of the block and the base of theblock is turned up to form a rib 31. In the block shown in Figure 3ridges 40 and- 4| are provided on each side of the base of thelolock.Inassembling the blocks in a roadwayor along. the roadway, dowel rods 42are placed in the grooves 3G and reenorcing rods 43 are securedto thedowel rods 42.. The reenforcing rods 43 may be laid in the road bed asshown in Figure 5 or they may connect 'to dead men not shown along thesideoi the road, by rods 44. When used for the latter purpose theysupport the blocks against the pressure ofk the bank forming the wallsof a tank such as shown in Figure 5 or the side of a roadbed to serve asa retaining wall as shown in Figure 6.

In the form shown in Figure 4 blocks 3l! are provided with their narrowsides adjacent each other and rest upon a bed of concrete 45 andpreferably are iilled at 46 with concrete or other road material'. YBetween the basesof the'y inner blocks 3U are placed clay or clayandcinders 4l and 48 to form a filler between the tracks of a roadway.Wheels of a motor vehicle are shown at 49 resting upon the drive-Waytracks.

In Figure 5 blocks 38 are used to form the Walls of a water tank orreservoir and are placed one upon the other, the lowermost of the blockshas reenforcing rods 43 attached to dowel rods 42. Rods 44 attached todowel rods on the back of all the blocks are attached to dead men, notshown, buried in the ground surrounding the tank. In order to provide vasmooth Wall around the reservoir a block 38 is positioned back of thetopmost block forming the edge of the tank anu a pipe or other drain 50is positioned between the blocks. The brick or other wall 5| provides aguard over the channel 50 and water freely ows over the topmost blockforming the wall and out through the opening 50.

In the form shown in Figure 6 a retaining wall is built up by two ormorelayers of blocks placed endwise against the back and alternateblocks inverted so as` to fit togetherfmore evenly. Upon these blocksare positioned blocks 38 which are anchored by rods 44 to dead men notshown. The front of the wall is built up of brick 64 so as completely tocover the face of the tier of blocks 38. v v v In the use of the blocksas illustrated in Figure 7 blocks 38 placed one upon the other form aretaining wall and are held in place by `rods which are secured to deadmen not shown.

j In Figure 8 only one block 38 is used in each case, the gutter isformed by two rowslof blocks 30 placed with theirnarrow .ends towardeach other so as :to `form achannelV which will serve as a gutter. `AThe blocks lmay be4 placed upon a hard under pan 52 ifdesired.

In the form shown in Figure 9: blocks 38 (are.

held to the ground by staples 54 and in this form the blocks preferablyrest upon a solid road bed 55.

In thev ,formv shown in Figure 10 concrete A53 may be poured into thegutter and ll the blocks up substantially to the level of the slots 34.

In the gutter shown in Figure 11 the block 39 iskused. l l

In the form shown in Figure 12 blocks 39 are used and are 4spaced apartand brick or other paving material 56 is placed between the walls ofside forms or blocks. Y v

In Figure'l `is showna new form of block which is designed for use as aroad marker,` surfacing form and screed. This block has the lower flange5'! and upper flanges 58 and may be made any desired length. Forpurposesof convenience the block has been indicated as marked intolengths of 2, 4, 6, 8 and 10 inches. The object of having a number ofdifferent lengths is for convenience in the making of street markers andsigns.

In the form shown in Figure 16 the block shown in Figure `15 is used.Blocks of suitable length are selected and placed together so 'as toindicate the word Stop. When placed in the road bed the blocks areembedded in the road but the block surface is of such material` and suchcolor as to make it durable as a block and conspicuous as a marker.l l

Figure 17 shows blocks arranged to indicate th legend Slow.

Figure -18 'indicates the arrangement to denote' railroad crossings.

Figure 19 indicates an arrow.

Obviously blocks could be arranged in any sultable or desirable mannerso as to indicate any sign or legend desired. The surface of the blocksmade of appropriate material and having the same consistency and colorthroughout, preferably whiteor yellow, are always conspicuous anddurable. Y l

Figures 13 and 14 show a form of die. or mold 4for makingthe block shownin AFigureB. With suitable changes obviously the die couldbe adapted tomake blocks Vshown in Figures 1 and 2.

Y The die consists of a disk of iron 51 having a. vent 58 therethroughwhich vvent is the shape of the v outside surfaceof theblock. Around thevent there is a protruding collar 59. Longitudinal ribs 60 are providedon the inside of the collar for forming the grooves 34 in the sides ofthe tile or block. In order to make the longitudinal channels3l, 32 and35 core pieces 6l are positioned within the collar. These core piecesare attached to bridge bars 62 which bars serve to space the cores-rand:to hold them in position. The bridge bar is attached toV the die plateinany suitable wayas by means kof bolts63.v

Figures20 and 21V illustrate a form of die tor making blocks shown inFigures 15gto l19 inclusive. Figure 2l shows a circular disk or iron 66having two cuts 61 inthe shape of the block shownin Figure 15 aroundwhich cuts thereis a collar 68 within which/the lolockmls` molded orcast. Corepieces 69 are mounted centrally of the collar and are. securedtobridgegbars 10 and 'Il Whichbarssupport'the cores in positioncentrally of the block. The bridge bars may be securedinarly``suitablgWy as by means oi bolts 'l2 to the disks 66. *The plates 66vmaybe Amade any shape desired so as to fit ina pugmill.

It will be obvious `to those skilled in the art that various changes maybe made in my'device without departing fromthe spirit oftheinvention andtherefore I do not r.limit myselfto what is shown in the drawings `andldescribed in thespecir cation, Vbutlonly as indicated bythe appendedclaim. y

Having thus fully described my said invention, what I claim as new anddesire. 'to secure by Letters Patent is:`

y A block of the character described comprising a body of substantiallyinverted T-shaped cross" section and having vertically Vspacedlongitudinal channels of relatively Vsmall -cross section extendingtherethrough, the side portions of the block being upturned andprovidingr lateral sup-.- porting and anchoring4 flanges of substantialr height and Vlateral area, the sides ,of the bodyV slopingtowardeach-other from the base to the top and being longitudinallygrooved to assist inv anchoring gthe` body in place the Aexterior'configuration `of vthe body being designed to provide anchorage,andimmobility of the block in they roadway. j
